A cursor positioning control device is provided. The device includes a cursor movement measuring unit configured to measure a measurement value corresponding to a movement amount of a cursor on a display every certain time, a cursor deceleration determination unit configured to subtract an N-th measurement value from an (N-1)-th measurement value of the cursor movement measuring unit, and configured to determine that the cursor is being decelerated if the subtracted value is greater than a predetermined threshold value, wherein N is a natural number. When the number of successive times that the subtracted value is greater than the predetermined threshold value exceeds a predetermined number of times, the cursor deceleration determination unit generates an instruction signal for at least further decelerating a movement of the cursor than a cursor movement deceleration speed that a user instructs.
